What our shortlists say about the one we picked.
Best for: F5 BIG-IP shops securing older web apps
It earns its place as the bridge for older apps, because it puts modern sign-in and MFA in front of them instead of rewriting them. It fits mid-sized and large companies that already run BIG-IP on premises. It works next to an identity provider rather than replacing one, so plan it as a second layer beside your main sign-in product.
